Spurting Active Region [hd video]

NASA image acquired October 9, 2011

 

A single active region shot out about a dozen small spurts of plasma over a day (Oct. 9, 2011). The STEREO Ahead spacecraft caught the action in extreme UV light as the region was beginning to reach the edge of the Sun, giving it a good semi-profile view. None of these were shots that produced any major solar storms, but it was still fun to watch the series of eruptions. The Sun is producing more sunspots these days as its level of activity continues to rise.
